Eco is a survival game in a global sense, where it is not just the individual or group who is threatened, but the world itself. The world of Eco will be home to a population of thousands of simulated plants and animals, each living out their lives on a server running 24 hours a day, growing, feeding and reproducing, with their existence highly dependent on other species.
Besides the threat of destroying the ecosystem of the world through pollution and habitat destruction, the world of Eco is threatened with another catastrophe, set via options at server creation. A meteor may be striking the earth, with the groups only chance of survival to develop technology to prevent it. Or a drought may be imminent, and food and water must be conserved in anticipation. Global warming may be raising the sea levels, and players will have to adapt. In Eco, the threats to the world’s existence are not only internal (player destruction of the ecosystem) but external as well, giving players an additional incentive.
